Saltstraumen is nothing less than the strongest tidal current in the world. Every six hours, during ebb and tide, more than 370 million cubic meters of salt water flows through the narrow strait that separates the Salt-fjord (yes, that`s its name) from the Skjerstad fjord.
All that water pressing through the 150 meter narrow strait at almost the same time, creates a huge water pressure which again creates the whirlpools. The whirlpools can be more than 10 meters (30ft) wide and 2 meters (6ft) deep! The whirlpools rotate with a speed of 20 knots. The current through the center of the strait flows with a speed of more than 8 knots on the surface.The fresh Atlantic water contains a rich and exciting marine life, which makes Saltstraumen the perfect place for fishing. In addition, National Geographics rated Saltstraumen amongst the top ten most spectacular places to go scuba diving, and Saltstraumen is also represented in the Wild Wonders of Europe. Saltstraumen was declared a maritime protection area in 2013.
